Place the pitted dates, pepitas, rolled oats, tahini, pure maple syrup, sea salt, and cinnamon into a food processor.
Process the mixture, stopping to scrape down the sides as needed, until it is mostly smooth and holds together when pressed—use short pulses and continue until the mixture clumps but is not overly wet.
If the mixture seems dry or crumbly, pulse a few more times and press a small amount between your fingers; repeat pulsing and scraping until it sticks together when squeezed. If the mixture becomes too sticky, pause and scrape into a bowl to cool briefly.
Spoon or pinch off portions and roll them between your palms into roughly 1-inch balls.
Pour the shredded coconut into a shallow bowl and roll each ball in the coconut to coat the outside.
Arrange the bliss balls in a single layer in an airtight container and refrigerate until firm, at least 30 minutes, before serving.
